Tasbi: A compact bracelet device capable of rendering complex multisensory squeeze and vibrotactile feedback

Augmented and virtual reality are poised to deliver the next generation of computing interfaces. To fully immerse users, it will become increasingly important to couple visual information with tactile feedback for interactions withthe virtual world. Small wearable devices which approximate or substitute for sensations in the hands offer an attractive path forward. Tasbi is a multisensory haptic wristband capable of delivering squeeze and vibrotactilefeedback. The device features a novel mechanism for generating evenly distributed and purely normal squeeze forces around the wrist. Our approach ensures that Tasbi’s six radially spaced vibrotactors maintain position and exhibit consistentskin coupling.
